TI  - Determining meaningful changes in gait speed after hip fracture.
PG  - 809-16
AB  - BACKGROUND AND PURPOSE: Older subjects after hip fracture walk more slowly than 
      age-matched peers. The extent to which they walk more slowly is difficult to 
      define because the standard error of the measure (SEM), sensitivity to change, 
      and clinically important change have not been reported for gait speed. The 
      purposes of this study were to quantify the SEM for habitual and fast gait speeds 
      among older subjects after hip fracture, to define the minimal detectable change 
      (MDC), and to estimate the minimal clinically important difference (MCID) for 
      habitual gait speed. SUBJECTS: A sample of 92 subjects after hip fracture was 
      drawn from 3 studies that collected gait speed data. METHODS: An estimate of the 
      MDC was determined by use of the SEM. The MCID was determined from expert opinion 
      and from a receiver operating characteristic (ROC) curve. RESULTS: The SEM and 
      the MDC were 0.08 m/s and 0.10 m/s for habitual speed and fast speed, 
      respectively. Both methods of MCID estimation identified 0.10 m/s as a meaningful 
      change in habitual gait speed. DISCUSSION AND CONCLUSION: The estimated MCID for 
      gait speed of 0.10 m/s was supported by clinical expert opinion and the cutoff 
      point of the ROC curve.
